However, the existing asphalt waterproof coiled material still has the problems of ageing resistance, large change of high and low temperature working performance and the like, so that the asphalt waterproof coiled material capable of meeting the working and using requirements of people and the building use requirements is urgently needed.
Disclosure of Invention
The invention aims to provide a super-adhesive SBS elastomer modified asphalt waterproof coiled material and a preparation method thereof, and aims to solve the problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme: the super-bonding SBS elastomer modified asphalt waterproof coiled material has the following characteristics: the super-adhesive SBS elastomer modified asphalt waterproof coiled material comprises a base, a low-viscosity SBS modified asphalt layer, a super-adhesive SBS modified asphalt layer and a release film, wherein the low-viscosity SBS modified asphalt layer, the super-adhesive SBS modified asphalt layer and the release film are sequentially coated on two sides of the base from inside to outside;
the super-adhesive SBS modified asphalt layer comprises the following components: asphalt, a filler softener, an SBS modifier, an antioxidant, a flame retardant, acrylic acid and carbon black;
the low-viscosity SBS modified asphalt layer comprises the following components: asphalt, filler, softener, SBS modifier and antioxidant.
Further, the super-adhesive SBS modified asphalt layer comprises the following components in parts by weight: 90-120 parts of asphalt, 15-40 parts of filler, 5-10 parts of softener, 10-20 parts of SBS modifier, 3-10 parts of antioxidant, 1-4 parts of polypropylene wax, 4-8 parts of acrylic acid, 3-5 parts of flame retardant and 5-10 parts of carbon black.
The polypropylene wax has the characteristics of high melting point, low melting degree and good lubricity and dispersibility, the melting point is between 130 ℃ and 170 ℃ due to different molecular weights, when the SBS modified asphalt layer with super-cohesive force is prepared, the polypropylene wax can be dispersed in the asphalt matrix after being heated and stirred, and plays a role in improving the high temperature resistance and the mechanical property of the asphalt matrix, after the asphalt matrix is cooled, the wax component in the asphalt can be gradually separated out, and the polypropylene wax can gradually drift to the surface of the super-adhesive SBS modified asphalt layer to be uniformly dispersed in the separation process, so that the surface of the super-adhesive SBS modified asphalt layer is protected by the wax layer, thereby preventing the SBS modified asphalt layer with super-cohesive force from directly contacting with water vapor, prolonging the service life of the asphalt layer, and the wax coating also has the characteristic of wear resistance, and can further improve the mechanical property of the SBS modified asphalt layer with super-cohesive force.
Further, the low-viscosity SBS modified asphalt layer comprises the following components in parts by weight: 100-120 parts of asphalt, 15-40 parts of filler, 10-25 parts of softener, 5-15 parts of SBS modifier and 3-10 parts of antioxidant.
Further, the base is any one of polyester tire and glass fiber tire, and the thickness is 1.2-1.5 mm.
Furthermore, triangular depressions are prepared on the outer side of the low-viscosity SBS modified asphalt layer (2), the depth of the triangular depressions is 0.2-0.4mm, the width of the triangular depressions is 0.1-0.3mm, and the interval of the triangular depressions is 2-5 times of the width of the triangular depressions.
Further, the asphalt is any one of No. 130 asphalt, No. 110 asphalt or No. 90 asphalt; the filler is any one or more of glass fiber, talcum powder, fly ash and calcium carbonate; the softening agent is any one or mixture of two of aromatic oil and cyclic hydrocarbon oil in any proportion.
The naphthenic oil and the aromatic oil are petroleum refining products like the asphalt, can be used as a byproduct for producing the asphalt and the asphalt to be used cooperatively, have good compatibility with the asphalt, can be used as a light component in the asphalt to play a role in reducing the viscosity of the asphalt after being doped into the asphalt, have good interaction force with the PB chain end inside SBS, can increase the motion trend of the PB segment, reduce the molecular deformation of SBS and further improve the fluidity of SBS.
The carbon black is an amorphous black substance generated after carbon element is incompletely combusted, and the main elements of the carbon black comprise carbon element, oxygen element and hydrogen element. As amorphous carbon, the carbon black has huge specific surface area, when the carbon black is added into the asphalt as a modifier component, redundant softener components in the asphalt component can be adsorbed by virtue of the surface area factor, and the phenomenon that the softening oil component is separated out in the use process to cause the reduction of the waterproof performance is avoided; after the carbon black is filled, the cracking phenomenon of the waterproof coiled material can be further avoided in the using process, the light components and the softening agent in the waterproof coiled material can be retained for a longer time due to the adsorption effect of the carbon black, the basic performance of the waterproof coiled material can be maintained for a longer time, in addition, the carbon black also has excellent ultraviolet absorption capacity, the aging phenomenon of organic components in the waterproof coiled material under the radiation of ultraviolet rays is reduced, and the service life of the waterproof coiled material is further prolonged.
Further, the antioxidant is any one of commercially available antioxidants TBY-2246, MD1024 or KY-405; the flame retardant is modified nano zinc oxide, wherein the preparation steps of the modified nano zinc oxide are as follows: adding nano zinc oxide into an ethanol solution dissolved with dodecyl trimethyl ammonium chloride, performing ultrasonic oscillation treatment with the frequency of 20-25KHz for 10-20min, and centrifuging to obtain the modified nano zinc oxide.
The nanometer zinc oxide is used as an inorganic mineral, is often used as a flame retardant to be added into various organic matters, improves the flame retardant effect of the organic matters, has the characteristics of high thermal stability, low toxicity, no corrosive gas generation and long flame retardant effect, and is a good flame retardant material.
The shielding capability of the nano-sized metal oxide powder to light is the largest when the particle size is 1/2 of the light wavelength, and the nano-oxidation property can show stronger ultraviolet light absorption capability than titanium oxide when the particle size is the same, and can realize shielding effect on long-wave ultraviolet rays and medium-wave ultraviolet rays in an ultraviolet light region, so when the nano-zinc oxide is added into the asphalt matrix, the ultraviolet light resistance of the asphalt matrix can be improved, and the performance degradation influence caused by ultraviolet light irradiation can be relieved.
When the nano zinc oxide is used as a flame retardant to be doped into the asphalt matrix, the nano zinc oxide can also play an antibacterial role, and the pseudo-unicellular bacteria and bacillus existing in nature have better decomposition capability on petroleum hydrocarbon substances and can decompose alkane and aromatic hydrocarbon contained in the asphalt matrix. When the nano zinc oxide contacts with the bacteria, zinc ions can be combined with cell membranes on the surfaces of the bacteria and react with hydroxyl and carboxyl contained on the bacteria to destroy the cell membrane structure, so that the aim of resisting bacteria is fulfilled.
Further, the SBS modifier is a mixture of star-shaped SBS and linear SBS, and the ratio of the star-shaped SBS to the linear SBS is (1.5-2.5) in parts by weight: (2-3.5).
The linear SBS and the star SBS can both play a role in modifying the asphalt component, improve the high-temperature performance and the low-temperature performance of the asphalt component, form a net structure in the asphalt component, improve the cohesion of the asphalt component and improve the viscosity of the asphalt component; compared with linear SBS, star SBS has larger relative molecular weight, high cohesive strength, better physical cross-linking, heat resistance and elastic modulus, and better modification effect on asphalt than linear SBS, but when the star SBS is used in too large amount, the cohesive force is too high, so that the whole shrinkage internal stress of asphalt is too strong, which is not beneficial to the dispersion and the paving of asphalt matrix, therefore, star SBS and linear SBS are often used in mixing.
Furthermore, the thickness of the low-viscosity SBS modified asphalt layer is 0.8-1.2mm, and the thickness of the super-adhesive SBS modified asphalt layer is 1.2-1.5 mm.
A preparation method of a super-adhesive SBS elastomer modified asphalt waterproof coiled material comprises the following steps:

In order to improve the binding power of the waterproof coiled material, the super-binding SBS modified asphalt coating is prepared, the binding power is good, but the viscosity is high, so that the combination of the coating and the tire base is not facilitated; the invention also carries out modification treatment on the base, uses the silane coupling agent to modify the surface of the base, and uses the ultrasonic oscillation mode to eliminate micro bubbles in the base, so that the base can be better combined with the coating during coating.
